15. Verify that all rectifiers are off before proceeding.
16. Reconnect ALL alarm cables J202 at the 208G boards for
all rectifiers.
17. Place a 20-ampere load on the battery plant; turn the ac
power switch on rectifier to On and adjust its output to
151.9 volts.
18. Turn off rectifier and load.
19. Repeat Steps 19 and 20 for all rectifiers.
20. Turn all rectifiers on with 20 amperes still applied. Wait
until batteries are charged and draw less than 5 amperes at
the rectifier displays.
21. At PDSC A1 (or B1), open ac circuit breaker #1. Verify
that power has been removed from the appropriate rectifier
(refer to Figure 2-1).
22. Operate breaker to On after test.
23. Repeat Steps 23 and 24 for all assigned circuit breakers in
both ac cabinets associated with the plant PDSC A1 or B1.
